Question about ViewSonic VA703B LCD Monitor

The monitor will not display or power up. I've

The monitor will not display or power up. I've checked to make sure the monitor is plugged into the computer and the power cable is connected and plugged in. The screen just went blank while my son was working on the computer. Is a lamp out or is it a problem with the LCD graphic card or something else?

There are two places to look for the problems, the backlight inverter board and the power supply, look for burnt parts, bad capacitors, etc.

Viewsonic VA1918wm-2 VS12085 intermitent display


If you have not updated the graph drivers, and it has been working, then you should contact View-sonic, go to their website, check warranty, but if you didn't change anything, it should be the monitor having problems. Did you check the plugs on the PC and monitor, the power plug on the monitor, make sure they are connected right and didn't come lose.

Hi! i am having problem with Display from motherboard. I had already checked ram, power supply but i didn't get any display. so how can i resolved this problem. Please help.....


I'm assuming this is a desktop motherboard? Make sure the plug for power is connected and tight. It is refuses to work see if you have another slot and try moving it to the free spot.

If it still doesn't work: 1. make sure your monitor is connected properly and turned on 2. if possible try the monitor on another machine to make sure it's not the monitor itself

If the monitor works correctly on something else and you've tried the above than it's likely that the video card itself died and needs replacing.

My proline notebook is not displaying even when plugged in to an external Monitor.


Hi,

When you plug in an external monitor, try to hit the combination Ctrt + F10 (or F7..depends on what key is designed for it. The key usually has a box picture on it) to make sure that you toggle displays between the laptop and the external monitor.

But if you've already done this but still didnt get any display, you can now go ahead and reinsert the memory module/s (RAM) of your laptop. A faulty or dirty memory module usually causes the unit not to POST (Power on self test). If you have 2 memory modules, try to gently clean the contacts using a pencil eraser and insert them one by one.

However, if this step will not resolve the issue, you need to consult help from an experienced technician. The video card of your computer is surely dead in this case.

Hope this helps.

No display on moniter


Check the following if you don't see a green light on the monitor

1-Make sure Power cord of monitor is plugged to the wall outlet directly and the other end to the monitor (don't use a powerbar for this test)
2-Make sure monitor is turn on

If you see an amber light on:
1-Make sure the data cable is plugged-in snugly to the monitor and to the video card.

If after you have checked the previous steps you still have a blank screen:
1-Check the adjustments and color settings of monitor
2-Plug the monitor onto another computer to test it

If the monitor works onto another computer, check your video card.

Apple monitor 20"


i’ve been repairing lcd monitor for awhile If you can or know someone that can take the monitor apart. check the power supply for caps that are bubbled there are bad. If you know how replace if not and know someone that does have them replaced. that should fix your problem the inverter circuit may or may not be on that power supply. if the two pair of lamp wires are plugged in then it all in one. replacing the caps work about 80% of the time. i would check and replace.
please let me know if this helps thank you.

Display problam


  1. Make sure that the monitor is turned on and has power. Make sure that the display's power cord is plugged into a working wall outlet, and that it's properly connected to the power adapter. (To check if the wall socket is working, plug in a lamp or other electrical device.)
  2. Check that all video cable connections to the computer video port and to the monitor are properly connected.
  3. Examine the pins on the video cable connector to make sure they are not bent or damaged in any way.
  4. Connect a known working display (if you have an extra one available). If you see video after doing so, replace your old display.
  5. Unplug the video cable and then turn on the monitor, check any message is showing in monitor if its shown means ur monitor is ok or else their is a problem in monitor..
  6. turn off the system and check the ram..
  7. Reset the computer...
